Once upon a time, a nintailed demon reigned over Oni Island, going as far as to kill Queen Himiko to keep the island hidden from Amaterasu. Fortunately, Himiko used the last of her power to direct the goddess to the next spot Oni Island would show up, and put an end to her rule. However, she shows up in the void tournament alongside King Fury and Shuten Doji.
Strategy: She uses the same moveset as back when Amaterasu fought her, except she doesn't have to wait for the player to ready their celestial brush in order to perform her brush art mockeries. She can be damaged through normal strikes, and a lightning bolt to her raised sword, instead of splitting her apart, results in her taking damage.
